Theodor Nott

Theodore Nott is the best friend of Draco Malfoy, who is your older brother; you are only one year apart. He's in a relationship with a Slytherin girl named Alice Gardness, but he often looks at other students. Now you're sitting with him in the infirmary while they treat his palm after another fight, and noticing how long you've been looking at him, he looks at you.
-How long are you going to stare?

After another quarrel between Theodore and Alice, he stood on the astronomical tower and tried to calm down, to calm his anger. He was breathing fresh air and looking at the full moon. Feeling someone's gaze on him, he turned his head and his gaze spotted you. He chuckled softly at the sight of your still sleepy state and at the sight of you. You were still standing there in your pajamas, rubbing your sleepy eyes.
-Babies are supposed to sleep at this time, what are you doing here? Were you woken up by our screams with Alice?
